A method for operating an in-vehicle charger and an in-vehicle charger mounted to a vehicle. The in-vehicle charger includes a charging coil for performing non-contact charging to a mobile device placed in the vehicle; and a control unit connected to the charging coil. The control unit instructs start or stop of supplying power to the charging coil in response to detecting a first signal indicating the engine is driven and a second signal indicating a state of a vehicle component of the vehicle other than the engine. The method includes a step of detecting the first signal; a step of detecting the second signal; and a step of instructing a start or stop of supplying power to the charging coil in response to detecting both of the first and second signals.

On the methods of creating corneocyte specimen for providing useful information for appropriate selection of cosmetic products or assessment of the skin condition, it is intended to provide a method of indicating an unstained image of corneocytes or the like in an observable pseudocolor in a method of creating corneocyte specimen, without resorting to staining the corneocyte specimen. The state of corneocytes of skin is input into a computer as an enlarged image by using, for example, a digital microscope. Then, the RGB values of the individual pixels in the image are converted with the use of a conversion system such as a conversion formula, a conversion table or a conversion chart and an image is indicated in a pseudocolor by using the individual RGB values converted.

Method of supporting the differentiation of corneocytes

Provided is an audio playback system, which reduces a restriction on a place of installation and which reduces the dispersion of characteristics of sound pressures in a low frequency range due to the seats in a passenger interior of a vehicle so that a comfortable bass sound can be enjoyed at any seat. The audio playback system comprises a first filter (), to which an audio signal outputted from a playback apparatus () is inputted, configured to pass a frequency band lower than a first-order resonance frequency of the passenger interior of the vehicle, a first sub-woofer () configured to receive an output signal of the first filter (), a second filter (), to which the audio signal from the playback device () is inputted, configured to pass a frequency band including the first-order resonance frequency of the interior, and a second sub-woofer (), to which an output signal of the second filter () is inputted, configured to be installed near a node of a first-order resonance mode of the interior.

Noise is prevented when decoding an audio stream not containing syncwords or CRC bits in the elementary stream. When decoding a current frame, the private header of the next frame is analyzed and the current frame is muted if the private header of the next frame is not valid. When there is a data discontinuity caused by editing, decoding resumes from the start address of the next frame determined.

This invention relates to an apparatus and method for embedding data in a signal or for updating data that has been embedded. The object of the invention is to provide a data-update apparatus that together with greatly reducing the amount of operation required for adding, detecting and removing data (electronic watermark) in a plurality of signals, makes it rigid copyright protection possible. In order to accomplish this objective, the present invention provides a data-update apparatus comprising: a channel-selection means that selects and outputs part of the channels of the input signal; a detection means that detects the electronic watermark that is embedded in the signal of the channel selected by the channel-selection means; a judgment means, to which the data detected by the detection means is input, and that determines whether or not to update the electronic watermark; an update-signal-generation means, to which an update instruction is input from the judgment means and to which the signal of the channel selected by the channel-selection means is input, and that outputs an update signal for updating the detected data; and a channel-selection-addition means that selects part of the channels of the input signal and adds the update signal to the selected channels.
